Question

True statement about the given condition of the eye except:

• A. Arise from any part of conjunctiva
• B. Can cause Astigmatism
• C. Surgery is treatment of choice
• D. UV exposure is risk factor

Hint:

Pterygium is always in the interpalpebral fissure, not just any part of conjunctiva.

Answer 1

The Correct Option is A

Step 1: The image shows a pterygium, a wing-shaped triangular fold of conjunctiva that encroaches onto the cornea within the interpalpebral fissure, most often on the nasal side. It is a non-neoplastic degenerative and hyperplastic condition.
Step 2: The question asks for the false statement ("except"). Pterygium is ALWAYS situated within the palpebral aperture and does NOT arise from any part of the conjunctiva, so option (a) is false and is therefore the answer.
Step 3: The other options are true. Encroachment on the cornea can flatten it and cause corneal astigmatism (b is true). Excess UV/sunlight exposure, dust, heat and wind are recognised risk factors (d is true). Surgical excision is the only satisfactory treatment for a progressive or symptomatic pterygium (c is true).
Step 4: Hence the medically correct false statement is that it can arise from any part of the conjunctiva.
